I'm only defending myself against the keyboard warriors. If it was dangerous, I wouldn't have done it. You'll also notice that it's as far away as possible from sources of ignition like the exhaust. The factory fuel line runs through that area (the unused tab shown in the photo is for the factory fuel line).
The most important things...Don't put connections above the exhaust, don't put them anywhere near the suspension where it could be traveled into, and avoid putting them in the wheelwell...and NOT in the passenger compartment.
I had to make an unavoidable connection to a flex line near the header for the return. I would not have done this on the feed line as it's at a much higher pressure and volume.
The gas isn't too dangerous until it has something to ignite it.
